The Verdict

Harness Power went out of business in 2023 and abandoned hundreds of customers mid-project. We analyzed more than a hundred reviews and found a company that routinely failed inspections, left systems nonfunctional for months, and then shut down without notice, leaving homeowners with $70,000 loans for useless panels on their roofs. One customer reported panels installed in July 2022 that still weren't working by February 2023 after repeated failed inspections. Another discovered 25 roof tiles simply weren't replaced after installation, leading to interior leaks that Harness refused to repair. The company also failed to pay subcontractors, triggering mechanic's liens against customer properties even after homeowners had paid in full. Communication was a disaster across the board. We found 53 mentions of unresponsive staff, broken promises to send specialists, and customer service reps who would say "we'll get right back to you" and then disappear for weeks. The 21 positive reviews all predate mid-2022, before the operational collapse became obvious.

If you're researching Harness Power because you found old marketing materials or a dormant listing, stop. The company is defunct. Any panels they installed come with worthless warranties and no support infrastructure. Look elsewhere.

3 Stories That Stood Out

1. hilary c.
Yelp | Feb 25, 2023 |

Hilary C. signed a contract on 10/26/2021 for an oversized solar array and a battery on her home — sized up so she could eventually power an EV and, she was told, “live off the grid” during peak hours. The crew finished the physical install on 12/28/2021, but what followed felt like a yearlong exercise in fixes, missed promises, and poor communication. She watched inspectors make five or six trips before the job finally passed, then waited months for permission to operate (PTO), which only arrived on 6/29/2022. The company emailed a sketchy how-to with pictures that weren’t even of her system after promising an in-person activation; she followed the directions and the system stayed dead. A technician arrived at the end of August and recommended swapping to a different set of equipment the company claimed to “know well,” promising an un-install and re-install in about two weeks. Before committing, she asked for specifications and a cost breakdown — none ever arrived. By October installers returned without the battery; the battery finally showed up in November and also failed to work. The company blamed improper wiring (wiring the crew had installed) and said a specialist was needed.

2. Stephanie F.
Yelp | Mar 25, 2023 |

Stephanie F. began a solar installation a year ago and ended up tangled in delays, failed inspections, and a company collapse. She bought a system that didn’t perform as promised, then spent months pushing the installer to fix problems and respond to questions. The crew mounted the panels in July 2022, but the first inspection didn’t happen until November because parts had to be swapped. That inspection failed, and the installer then spent about three months reworking plans to meet the city’s requirements. An inspection was set for last week but was postponed by rain — and then, on Friday, customers discovered the company had gone out of business without notifying them. Now she faces more than $70,000 in loan debt with payments starting in July, while nonworking panels sit on her roof and she scrambles to get the inspection completed and the system activated. She’s hopeful the project can be finished but is unsure about legal options; the hard, memorable fact is this: loan payments will begin before the system is even approved to run.

3. Sarah G.
Yelp | Feb 15, 2023 |

Sarah G. had a residential solar system installed in November 2022 and was cleared to turn it on in December. By early February she received notice that a mechanic’s lien had been recorded against her property because the installer hadn’t paid a subcontractor. She contacted the company immediately; they asked for 48 hours to review the account and promised to respond, but a week passed with no word. When she called again, the representative requested documents, which she provided within 15 minutes, and then the company went silent once more — three days of follow-up produced no response. She discovered the subcontractor could foreclose on the house based on that lien even though the company had taken cash in full at installation. The most striking detail: despite prompt payment from her side, the project’s unpaid subcontractor left a recorded lien that the installer did not resolve or even acknowledge after repeated contacts, putting the home’s title at risk.

What You Can Expect

01

1. Jason R.
Yelp | Jan 25, 2023 |

Jason R. had a residential solar array put on his roof in September and discovered the system held up through the area's wild weather — including aggressively high wind — while delivering strong output and noticeably lower electricity bills. He appreciated that Nicole G. walked him through different production scenarios, kept him updated through the project lifecycle, and routinely answered lingering questions via text and email later in the day. It wasn't flawless — he acknowledged the normal hiccups that come with a major construction job — but the panels have been performing well and the prompt, after-hours responsiveness from Nicole is the detail he remembers most.

2. Marlen The Realm Inc
Google | Aug 9, 2024 |

Marlen bought a rooftop solar system in 2019, paid $10,000 up front and was promised a lifetime warranty. When the panels stopped producing in September 2023, they called the service number expecting support and discovered an automated menu that steered callers to unrelated services — lifeline callers, addiction specialists, pest control, Dish Internet and car insurance — instead of any solar help. They learned the system was originally installed by Larsun, which had been acquired by Harness Power, but Harness Power now appears to be closed out for business, leaving no clear successor to honor the warranty. After hitting that dead end, they ended up with a nonfunctional array, a claimed lifetime warranty that they cannot access, and no obvious way to get the $10,000 investment serviced.

1. April B.
Yelp | Jan 22, 2023 |

April B. reached out to add extra solar panels to her roof and ended up working closely with Kody, who managed the project. She found him unusually responsive—answering questions by email and text at all hours— and he even arranged a bill-pay service while the system waited to be activated. When that part of the company turned out to be slow, Kody took matters into his own hands: he picked up her reimbursement and hand-delivered it to her. What stayed with her was his work ethic and personal follow-through—more than paperwork, he made sure she wasn’t left waiting.

3. Bridgett S.
Yelp | Feb 24, 2023 |

Bridgett S. signed a contract in October 2021 for solar on her home and ended up with a system that still doesn’t work properly. She discovered panels had been installed incorrectly and then watched the company bungled two different battery installs. Repeated calls, emails, and texts went unanswered or unresolved, and despite asking them to call before sending anyone over, the crew kept showing up unannounced — even though side gates are locked and there are dogs in the backyard. She asked Harness to reimburse her electric bills, loan payments, and the wages she lost staying home for appointments, but those requests were denied. After trying to get the company to fix the problems directly and getting nowhere, she wrote the review to warn others and to push for better service; the image that stuck with her was technicians arriving without confirmation while her property was secured and pets were at risk.

1. Brian S.
Yelp | Mar 10, 2022 |

Brian bought a roughly $41,000 solar system from Larsun Solar (now Harness Power) for his Temecula, CA home in December 2020. About a year later, while rushing to sell the house because military orders were sending him overseas, a home inspector discovered nearly 25 heavy roof tiles missing from a section that didn’t appear in the project completion photos — and there was no tile debris anywhere. The missing tiles exposed the roof paper for more than a year and led to a living-room leak. He contacted Larsun right away. Initial contact felt professional: on February 18, 2022, Posese Pulu called, agreed it looked like an installer oversight, and promised to get crews out to replace the tiles. Brian also explained the underlayment had been compromised and needed replacement. Larsun scheduled a visit for February 21, which was cutting it close to escrow closing on February 23, but seemed workable. On the morning of February 23, an email arrived saying Larsun would replace the tiles but would not replace the paper underneath. Brian called for an explanation; Pulu answered, said he didn’t know the reason, asked to find out, and then the call ended after a few minutes with no follow‑‑

2. Ralph D.
Yelp | Oct 21, 2022 |

Ralph D. began the process with Larsun before Harness bought the company and endured a drawn-out permitting fight with the city during COVID. He finally got rooftop panels installed and producing power, but quickly discovered a bigger problem: the electricity the system generated didn’t match what Edison’s meter was reporting. He had hoped the array would produce enough to allow him to buy and charge an electric car without incurring extra utility costs, but if he charged at home he would still be billed — which defeats the point of the system. For more than a year he has pushed both Larsun and now Harness to investigate. Company staff have been pleasant and acknowledged a variance; they said a tech would be sent out to check, but the site visit still hasn’t happened. The detail that stands out for him — and what a prospective buyer should notice — is that the panels themselves are up and making power, but an unresolved meter/reporting discrepancy and the long delay for a technician have prevented him from realizing the one concrete benefit he expected: cost-free home EV charging.

3. steve h.
Yelp | Oct 18, 2022 |

Steve began the project in October 2021, hiring a Los Angeles–based company to install panels and a Generac battery on his Marin County home, expecting a quick turnaround. Instead, the job stretched out — it took more than ten months to finish — and he spent additional months waiting for the city inspection and permission to operate because Harness repeatedly dropped the ball on permit and PTO applications. When the system finally received PTO last month, he soon started getting two PV Fault errors. Generac diagnosed the problem as two malfunctioning SWAP SNAPS (the connectors between panel arrays) and instructed him to contact Harness for repairs. After lengthy delays and what he describes as very poor customer service and support, he’s left with a completed system that’s already throwing faults and no reliable point of contact to resolve the faulty connectors, so he’s weighing other options.
